Husqvarna YTH2148 Vanguard Model L021H48F

Howdy, waiting for Hay to dry. I thought I would pick ur brains on a few problems with the above. I'm now in possession of two of the above. One has a "seized' up transaxle ( sealed throw-away) with rear wheels "locked". What is the "easiest" way to make the carcass moveable. Seems strange that noone has been inside to fix or repair these things??? Throw away society I guess???
Problem 2: electric clutch (pto) for mower deck is stuck...if u engage it kills engine. Is this simalar to a magnetic a/c clutch in a car??? Do they "rust up"? I never was in one. Do they come apart? Any quick fixes???
I have searched a few sites about this, and I'm just not feeling real good about these "lawn mowers". Thanks, JoeB
